MCP Servers for Claude Code

A curated list of Model Context Protocol servers to enhance Claude's capabilities as a personal assistant.

What is MCP?

Model Context Protocol (MCP) is an open standard that enables AI models to securely interact with external data sources and tools through standardized server implementations.

Recommended MCP Servers

Priority for Installation

For personal assistant capabilities, recommended priority order:

  1. Wolfram Alpha - Essential for math and computation
  2. Google Calendar or Apple Calendar - Calendar management
  3. Todoist or Google Tasks - Task management
  4. Rube or MintMCP - Multi-app integration (email, etc.)

Next Steps

  • Choose preferred calendar server (Google vs Apple)
  • Choose preferred todo server (Todoist vs Google Tasks vs Things 3)
  • Obtain additional API keys (Google Calendar, Todoist, etc.)
  • Install and configure selected servers
  • Test additional integrations with Claude Code

Installation Guide: Wolfram Alpha MCP Server

Prerequisites

  • Python 3
  • uv package manager installed
  • Wolfram Alpha API key (free tier: 2,000 calls/month)

Step-by-Step Installation

  1. Get API Key

  2. Clone Repository

    cd Personal/Areas/MCP-Servers
git clone https://github.com/ricocf/mcp-wolframalpha.git
cd mcp-wolframalpha

  3. Install Dependencies

    uv sync

  4. Create .env File Create .env in the repository root:

    WOLFRAM_API_KEY=your_api_key_here

  5. Configure MCP Server Create/update .mcp.json in your project root:

    {
  "mcpServers": {
    "WolframAlpha": {
      "command": "uv",
      "args": [
        "--directory",
        "/absolute/path/to/mcp-wolframalpha",
        "run",
        "python",
        "src/core/server.py"
      ],
      "env": {
        "WOLFRAM_API_KEY": "your_api_key_here"
      }
    }
  }
}

  6. Enable in Claude Code Settings Add to .claude/settings.local.json:

    {
  "enableAllProjectMcpServers": true
}

  7. Restart Claude Code The MCP server will be loaded on next startup.

  8. Verify Installation Ask Claude to perform a calculation using Wolfram Alpha!
